A Euler-Lagrange model of dynamic internal friction is proposed and is Hats shown to match the frequency and decay of oscillations in both simple extension (pull) and cantilever beam experiments.The proposed dynamic internal frictional stress, τij, is proportional to the rate of change of the engineering stress, σ˙ij.i.e.τij=μmσ˙ij,with μm
The change of energy structure brings new challenges to the Hats operation and planning of the power system, which requires the support of refined production simulation and evaluation techniques.Firstly, a scenario set generation method based on clustering coupling is proposed to generate typical operating scenarios of the power grid.Secondly, this
The liver is an important metabolic and detoxification organ and hence demands a large amount of energy, which is mainly produced by the mitochondria.Liver tissues of patients with alcohol-related or non-alcohol-related liver diseases contain ultrastructural mitochondrial lesions, mitochondrial DNA damage, disturbed mitochondrial dynamics, and comp
Adherence at the earliest stages of treatment is likely to be influenced by prior illness trajectories and future expectations, best captured (and addressed) before treatment begins.We examined the influence of illness trajectories and treatment expectations on psychosocial readiness to start antiretroviral therapy (ART) in Jinja, Uganda.In-depth i
The DSM, or Dispute Settlement pedal arm pivot Mechanism, in the absence of a judicial body, is the closest representation of a supreme court or judicial institution in a regional bloc or other international organisation.The search for a peaceful settlement of disputes in the international arena had led to the development Rompers of the DSM during
